Ionizing Radiation Escape from Low-Redshift Galaxies and Its Connection to Cosmic Reionization
Anne E. Jaskot
The escape of Lyman continuum (LyC) radiation from early galaxies transformed the intergalactic medium (IGM) and is intimately connected to the fueling and feedback processes that…
The Merger-Driven Formation of Classical Low Surface Brightness Galaxies in Romulus25
Anna C. Wright, Alyson M. Brooks, Michael Tremmel +3
We use the Romulus25 cosmological simulation volume to study a large sample of late-type gas-rich galaxies with low central surface brightnesses known as classical low surface brig…
Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions
Casey Papovich, Justin W. Cole, Weida Hu +27
Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…
The Lyman-alpha and Continuum Origins Survey II: the connection between the escape of ionizing radiation and Lyman-alpha halos in star-forming galaxies
A. Saldana-Lopez, M. J. Hayes, A. Le Reste +24
One of the current challenges in galaxy evolution studies is to establish the mechanisms that govern the escape of ionizing radiation from galaxies. Here, we investigate the connec…
Halfway to the Peak: The JWST MIRI 5.6 micron number counts and source population
Leonid Sajkov, Anna Sajina, Alexandra Pope +9
We present an analysis of eight JWST Mid-Infrared Instrument (MIRI) 5.6 micron images with depths of ~0.1 uJy. We detect 2854 sources within our combined area of 18.4 square…
Linking Mg II and [O II] spatial distribution to ionizing photon escape in confirmed LyC leakers and non-leakers
Floriane Leclercq, John Chisholm, Wichahpi King +29
The geometry of the neutral gas in and around galaxies is a key regulator of the escape of ionizing photons. We present the first statistical study aiming at linking the neutral an…
